現(xiàn)場接地常用注意事項(xiàng)
DCS系統(tǒng)對接地要求比較嚴(yán)格，在現(xiàn)場接地時一定要嚴(yán)格按照DCS廠商的接地規(guī)范嚴(yán)格接地，否則會影響DCS系統(tǒng)的可靠性。對DCS系統(tǒng)現(xiàn)場接地時應(yīng)注意以下幾點(diǎn)：
(1) I/O柜的電源地與UPS的電源地必須接至同一個地，保證等電位。
(2) 接地電纜必須符合DCS廠商的要求，并要接到機(jī)柜內(nèi)的接地螺絲上。
(3) 系統(tǒng)接地與屏蔽接地不能在機(jī)柜匯合，必須單獨(dú)接入到接地網(wǎng)。
(4) 柜間接地不能用機(jī)柜并接螺栓代替，必須用接地線嚴(yán)格連接。
(5) 接地要牢固可靠，匯流連接板并要涂防腐漆。
(6) 接地電阻符合DCS系統(tǒng)要求，并要進(jìn)行嚴(yán)格的測定。
(7) 接地嚴(yán)格按照DCS廠商接地要求接地，不能為了省事走捷徑或不按照接地線線徑要求進(jìn)行接地。
